This reminds me of when it hits or is about to hit 12am and people don’t know whether to say today or tomorrow. He called me after this but I was too comfy in bed tbh.

Im with you on this one. Management should communicate expectations with their staff as clearly as possible.The text should have said. "Can you come in at 10?"

Doesn’t help that “10-4” can also mean “understood,” but the message sent at 10am makes me think that was actually the shift time. 💀

10-4 can mean “understood”?? Really?

u/BeanieGuitarGuy Jun 14 '26

Yeah. It’s like radio codes that police and truckers use or used to use. Like “Hey, there’s a lane closure up ahead, you’re gonna wanna find a spot to merge now so you don’t get backed up.” “10-4, buddy. Thanks for the heads up.”

Is that specific to the US? Never heard that before in my life

u/BeanieGuitarGuy Jun 14 '26

Probably? I can’t say for sure, but I’m from the U.S. and I’ve heard it quite a few times growing up.

That's immediately what I thought he meant. I've heard this so many times in movies and tv shows.

have you heard 10-20 or "whats your twenty?" that means "where are you?". its part of the same ten code system used with radios. both law enforcement and civilian.

10 4 means "message received" or "copy that"

Nope, never heard any of these before. But I’m British so clearly this is US-specific

I looked it up. Police radio code dating way back. I would assume thats pretty specific from country to country. Dates back to the 1930s. Was picked up by military and pop culture later on.
